11 year-old Harry has thanked a total stranger for giving his little brother a second chance of life, by offering to donate their stem cells later this month.

The Branthwaite family, from Bolton, are calling for more people to sign up to the Anthony Nolan stem cell register after finding out their toddler Freddie, who desperately needs a stranger to save his life, has found a match. His big brother Harry shared some touching words for the stranger who will become Freddie’s superhero.
